Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluidized solidified soil production, specifically a mixing device for fluidized solidified soil production. Background Technology
[0002] In the production process of fluidized solidified soil, the purity and mixing uniformity of the base aggregate directly affect the performance of the final product.
[0003] In existing fluidized solidified soil production mixing devices, the feeding structure often lacks an effective impurity filtration mechanism. Large particles of impurities mixed in the foundation aggregate can easily enter the mixing tank directly, which not only affects the uniformity of mixing, but may also lead to a decrease in the fluidity of the solidified soil, or even cause problems such as equipment jamming and wear. Even if some devices are equipped with simple filtration components, they often suffer from low screening efficiency and inconvenient impurity cleaning.
[0004] Therefore, there is an urgent need for a feed filter structure that can efficiently filter impurities, is easy to clean, and does not affect the continuity of production, in order to meet the high-quality and high-efficiency production requirements of fluidized solidified soil. Utility Model Content
[0005] The purpose of this invention is to provide a mixing device for producing fluidized solidified soil, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing fluidized solidified soil, comprising a mixing tank for mixing fluidized solidified soil, a mixing shaft in the middle of the mixing tank, mixing blades on the mixing shaft, a motor fixedly connected to the top of the mixing tank and cooperating with the mixing shaft, a feed hopper for adding basic aggregates on the top of the mixing tank, a filter assembly for preventing large particles of impurities from entering the feed hopper, the filter assembly including a screen installed on the feed hopper, the screen being inclined, a slag discharge pipe on the side wall of the feed hopper and at the bottom end of the screen, the slag discharge pipe being inclined, and a blocking component inside the slag discharge pipe.
[0007] Preferably, the blocking component includes a baffle that is slidably disposed inside the slag discharge pipe, and the other end of the slag discharge pipe is provided with a telescopic rod, and the output end of the slag discharge pipe is connected to the baffle.
[0008] Preferably, the bottom wall of the slag discharge pipe is provided with a slag discharge port, and a detachable collection box is provided below the slag discharge port.
[0009] Preferably, a guide plate is hinged to the upper middle part of the feed hopper, and the bottom end of the guide plate is inclined toward the upper middle part of the screen.
[0010] Preferably, the feed hopper has a frame plate in the middle for supporting the bottom of the guide plate, the bottom of the guide plate has a fixing rod, and the frame plate has a sleeve that engages with the fixing rod.
[0011] Preferably, a positioning post is provided on one side wall of the feed hopper, and a barrier net for blocking large-volume foundation aggregate is provided between the positioning post and the frame plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, by setting an inclined screen and matching slag discharge pipe, blocking components and collection box, the screening of basic aggregates and the removal of large particle impurities are realized. The inclined screen design causes the material to slide automatically under the action of gravity and complete the screening, avoiding large particle impurities from entering the mixing tank and affecting the fluidity of the solidified soil. The blocking components can flexibly control the opening and closing of the slag discharge pipe. Together with the slag discharge port and collection box, impurities can be discharged in real time and are easy to clean up. This effectively reduces the problem of uneven mixing caused by impurities clogging or mixing in, and improves the production quality of fluidized solidified soil.
[0014] 2. In this utility model, the stability and maintainability of the feeding and screening process are further optimized through the synergistic effect of the guide plate, frame plate, and screen. The inclined guide plate ensures that the material falls accurately into the upper part of the screen, extending the screening path to improve screening efficiency. The snap-fit structure of the frame plate and the sleeve facilitates the rotation and opening of the guide plate, while the screen can additionally filter out fine impurities and improve the purity of the collected material. The detachable design of each component reduces the difficulty of cleaning the inside of the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] All electronic components in this application are controlled by an external controller, and all electrical appliances in this application are powered by a stable power supply that is compatible with them.
[0023] Example 1: Please refer to Figure 1-5 As shown, this utility model provides a mixing device for producing fluidized solidified soil, including a mixing tank 1 for mixing fluidized solidified soil. A mixing shaft 2 is located in the middle of the mixing tank 1, and mixing blades 3 are mounted on the mixing shaft 2. A motor 4, which cooperates with the mixing shaft 2, is fixedly connected to the top of the mixing tank 1. A feed hopper 5 for adding basic aggregates is located at the top of the mixing tank 1. A filter assembly for preventing large particles from entering is provided on the feed hopper 5. The filter assembly includes a screen 6 installed on the feed hopper 5, which is inclined. A slag discharge pipe 7 is located on the side wall of the feed hopper 5 and at the bottom end of the screen 6. The slag discharge pipe 7 is inclined, and a blocking component is provided inside the slag discharge pipe 7. The blocking component includes a baffle 8 slidably disposed inside the slag discharge pipe 7. A telescopic rod 9 is provided at the other end of the slag discharge pipe 7, and the output end of the slag discharge pipe 7 is connected to the baffle 8. A slag discharge port 10 is provided on the bottom wall of the slag discharge pipe 7, and a detachable collection box 11 is provided below the slag discharge port 10.
[0024] The stirring shaft 2 is rotatably connected to the middle of the mixing tank 1, and the stirring blades 3 are fixedly connected to the stirring shaft 2. The motor 4 can be a common geared motor. The motor 4 can stir the fluidized solidified soil raw material inside the mixing tank 1 by rotating the stirring shaft 2 and the stirring blades 3. The feed hopper 5 can be used for feeding the basic aggregate. The screen 6 is placed at an angle in the middle of the feed hopper 5. The slag discharge pipe 7 is fixedly connected to the side wall of the feed hopper 5 and communicates with the inside of the feed hopper 5. Large particles separated by the screen 6 will enter the slag discharge pipe 7 and be discharged to avoid large particles affecting the material. To improve the fluidity of the solidified soil, baffle 8 is slidably connected inside the slag discharge pipe 7. Telescopic rod 9 can be purchased directly from the market. The extension and retraction of telescopic rod 9 can drive the extension and retraction of baffle 8, which can block the slag discharge pipe 7 and prevent materials from directly entering the slag discharge pipe 7. Slag discharge port 10 is opened at the bottom of slag discharge pipe 7. By moving baffle 8 to both sides of slag discharge port 10, it is possible to switch whether large particles are discharged through slag discharge port 10, which facilitates the cleaning of large particles inside. Collection box 11 is snapped into slag discharge port 10. When there is too much material in collection box 11, it can be removed and replaced.
[0025] Specifically, a guide plate 12 is hinged to the upper middle part of the feed hopper 5. The bottom end of the guide plate 12 is inclined toward the upper middle part of the screen 6. The guide plate 12 is hinged to one side wall of the feed hopper 5. The inclined arrangement of the guide plate 12 allows the material to fall into the upper middle part of the screen 6. The material can move toward the lower end of the screen 6 by its own gravity. The material can be screened while moving on the screen 6. The hinged guide plate 12 can be easily opened, which facilitates cleaning of the inside of the feed hopper 5.
[0026] The feed hopper 5 has a support plate 13 in the middle for supporting the bottom of the guide plate 12. The bottom of the guide plate 12 has a fixing rod 14. The support plate 13 has a sleeve 15 that engages with the fixing rod 14. The support plate 13 is fixed to the middle of the feed hopper 5, and the fixing rod 14 is fixed to the top of the support plate 13. The sleeve 15 is C-shaped and the slot is made of elastic wear-resistant plastic, which can easily hold the fixing rod 14 and facilitate the fixing and separation of the guide plate 12.
[0027] Based on the above embodiments, specifically, a positioning post 16 is provided on one side wall of the feeding hopper 5, and a baffle 17 for blocking large-volume foundation aggregate is provided between the positioning post 16 and the frame plate 13. The positioning post 16 is fixed to the inner wall of one side of the feeding hopper 5, and the baffle 17 is placed between the positioning post 16 and the frame plate 13. It can separate slender impurities (such as plant stems, leaves, roots, etc.) in the material. The baffle 17 can also be separated from the frame plate 13 and the positioning post 16 to facilitate cleaning the inside of the feeding hopper 5.
[0028] Working principle: When in use, the basic aggregate is first put into the feed hopper 5. At this time, the material will fall to the upper end of the screen 6 by the guide plate 12. The material at the upper end of the screen 6 will move downward due to its own gravity. During the movement, the smaller particles will fall into the mixing tank 1, and the larger particles will continue to move downward on the screen 6. When there are too many large particles, the baffle 8 is pulled back to the side away from the discharge hopper by the telescopic rod 9. The large particles at the bottom of the screen 6 will enter through the discharge pipe 7 and be discharged from the discharge port 10 into the collection box 11.
